To all whom it may concern.

Be it known thatI, ALEX NDER S.,' SPIE- GEL, acitizen of the United States, residing at Chicago, Illinois, have invented certain new and useful lmprovementsin the Manufacture of Shingles, of which the following is a specification.

The present invention pertains to the mit their being laid close together and thus prevent 'theexistence of open spaces, as in the case oftheordinary" shingles. a

A further object ofthe invention is to so cut the strips'of stock into shinglesof the desired form as'to avoid all waste of material. The simplicity of :the" operations'is such that it can be conducted-very rapidly.

with an enormous out utoishingles .in' a comparatively short in rval oftime.

' A still further advantage which the present method possesses over previous ones is that itproduces shingles all of the same shape and fsize. There are no odd shingles v to be used in filling in corners, no imper- .fectly formed. ones, and no' reverse ones according to the present inventlon.

2 shows how the shingles are laid in series upon a roof and Fig. 3 -shows a' sheet of the material which iscut' first into strips and then into shingles, It is the aim of the inventionto produce an attractive form'of shingle; one Whichmay bem-chea l imade without loss of material or'waste, and which may be laid close together to prevent any. crevices between.

As shown in. Fig.3v 3, a sheet of material of several times the width ofa single.

longitudinal slits, a, (1 extending on either a tide of the center of the strip and connected by a short diagonal'slit b. A second set of cutters is carried on the same shaft of the machine which will, cut the sheet into straight strips 1, along the lines 0. According to this arrangement the adjacent longitudinal slits or cuts a, a of the several series do not connect, being ofiseta slight distance from one another. The adjacent ends of theseslits i, a do not terminate at opposite points on thesanie transverse line (show-n at (Z in dotted lines),- but ex tend slightly beyond it in opposite directions. Thus the ends" of the slits a of one series in a sense, overlap the adjacent ends of the slits a of the next series. The longitudinal strips are now passed in the path of a rotarycutter which cuts transversely or laterally on approximately the lines (l severing'the strips 1 into separate shingles. By allowing the adjacent ends of the longi- "tudinal slots at and a to slightly overlap Patented Feb. 15, 1916. i

the transverse cuts d can be made with greater rapidity and much more' efiectively than would be the case if a careful degree of precision and accuracy had to be used to insure exact alinement with the two ends 'of t-and a.

Great numbers of shingles can'be quickly: turned out by this method and further more, each'shingle is an exact duplicate of the-other cut from the, adjoining piece of arranging of the layers'in constructing the roof. 1

What I claim is I the strip. Thus there will be no left hand i g .or right hand shlngles, requiring alternate In the -accompanying drawing: Figure I shows the improved formof shingle. (Fig.
